Abstract: A video recorder contains in its luminance transmission channel (8), in addition to the conventional circuit arrangements, a phase synchronisation arrangement (21) which is controlled by a start arrangement (22). In dependence thereon, the phase synchronisation arrangement synchronises the phase error of certain oscillations which are generated by the frequency modulator (10) of the transmission channel (8) from the amplitude-modulated luminance signal at the signal output (11) of the frequency modulator, with a reference oscillation. As a result, Moiré interference in the picture reproduction of video pictures recorded on a recording medium (7), generated by the different phase angle of adjacent oscillations of adjacent video lines, is largely avoided. <IMAGE>

Abstract: A baler machine including a charging chamber for receiving material to be baled. The charging chamber has a charging passage through which material is forced into a baling compression chamber by a compression ram to thereby form a bale in the compression chamber. An ejection ram is provided for forcing the compressed material out of the baling compression chamber through an exit passageway. A movable decompression wall functions as one wall of the baling compression chamber. Such wall is located opposite and spaced from the charging passage through which material is forced from the charging chamber. A power cylinder is provided to move the decompression wall in a horizontal direction to effectively increase the volume of the baling compression chamber which, at the same time, increases the size of the exit passageway to thereby permit ejection of an oversized bale from the compression chamber.

The active layer includes a layer having a crystal composition in which a lattice constant of the layer is different from a lattice constant of the first conductivity type substrate by 0.1 percent or more so that a strain may be applied to the layer. Therefore, a threshold current is significantly reduced, resulting in a high power semiconductor laser capable of operating at a high temperature.

Abstract: The invention provides for protecting floating blocks of text or other portions of a shared data object in collaborative computer based system from simultaneous manipulation originating with two or more users. The collaborative computer based system includes a network connecting a plurality of terminals for communication. Each terminal includes an output display device and a user input device. A shared data object (116) is simultaneously accessible by a plurality of users of the system. Responsive to a user obtaining access to the shared data object, the user is assigned a cursor (130, 138, 140) available for display on the visual display devices of all current users. Responsive to movement by a user of his or her cursor, an attempt is made to establish a lock region (142, 134, 123) in the shared data object by determining position coordinates. If the position coordinates do not include any portion of any previously established lock region, a lock region associated with the user's cursor may be established. Movement of a cursor operates to release any prior lock region associated with the cursor if a new lock is established or if the cursor leaves the old lock.

Patent EP-0551967-A2 (EP)
Inventor: KEELING MICHAEL R
IPC: B41J2/175
Filed: 1988-10-28
Abstract: An ink jet printer automatically adjusts the amplitude of the modulation signal applied to a transducer (159) to break the ink jet into droplets. Correct modulation amplitude is determined from changes in jet break-up length, as determined by changes in jet break-up phase relative to the modulation signal. 
     The printer has interchangeable print heads (3), which may have different nozzle sizes. A calibration code, specifying the particular values of ink pressure, jet velocity and charge correction required for optimum performance of a particular print head (3), may be entered into control logic (93), which operates the printer accordingly. 
     Most print head components are mounted on a mounting substrate (111), with all connections being made to the underside of the mounting substrate (111) and sealed with a potting compound, to avoid damage. 
     Ink viscosity is controlled in response to ink pressure, which is in term controlled in response to ink jet velocity. Thus all three parameters are maintained without the need for a viscosity meter. Ink jet velocity is sensed by means of signals induced by charged drops on spaced apart sensors (89, 91), the outputs from which are wired together and fed to a common comparator (105), which simplifies construction. 
     Internal conditions of the printer are output in response to interrogation. This permits remote fault diagnosis, e.g. over the telephone. 
     Ease of operation is improved because the printer automatically performs the tests and operations required when starting and stopping the jet, and it automatically performs a nozzle cleaning routine when sensor inputs indicate a nozzle blockage. 
     The ink gun (75) has an ink cavity (145) which tapers away from a bimorph piezoelectric crystal (159) which is restrained from flexing at one radius only. The gun is highly efficient and versatile, may operate at a range of frequencies and a range of nozzle sizes, and is preferably operated off resonance. 
     Dot patterns for printed characters are stored in a character store (175), and charging electrode levels are stored in a charge level store (177), with several alternative levels being stored for each dot position for use according to whether other nearby dots are being printed. This provides compensation for the electrostatic and aerodynamic effects of ink droplets on one another. Similar compensation for unprinted droplets is provided by a historic correction store (179). The provision of guard drops is controlled by a sequencer (185). 
    
     The voltage applied to the charging electrode (127), is compensated for variations in charging circuit amplification and jet-to-electrode capacitive coupling.

Abstract: A record material comprises a substrate bearing microcapsules having nonmeltable walls. The microcapsules contain a chromogen or developer and a photosensitive composition which undergoes a change in viscosity upon exposure to actinic radiation. The walls of the microcapsules have an elongation of not more than 1%, and the record material is resistant to heat, measured by not producing any substantial color when placed in a 150°C oven for one minute. Surprisingly, the record material however is capable of forming a color upon application to the record material of a point source energy input comprising a Δ T of at least 115°C per one millisecond. The record material can be desensitized, i.e. made not susceptible to further imaging, by exposure to actinic radiation.
